Um the aps twins come with downpipes..you need to buy a ypipe ,hooker is supposed to work or make your own dual exhaust. I am just going with hooker yipe I think and my b and b catback with electric cutout for now and see how that works out.

With the 3" down pipes I would use 3" custom duals. That's what I'm doing.

3" DPs will be fine, if your really worried, dont run a y setup and stick to 3" duals....

The twin 3in downpipes can allready support more power than those turbos are capable of so you would see no gain in changing them.
